IC1396 thru IDAS NB1

This is unguided 10 x 3′(ISO 4000) shots with NB1. It seemed to be under-exposure. 5 – 6 minutes at normal ISO looks more suitable.


IDAS NB1 + BORG 107FL F3.9ED + Cooled 6D, no dark/flat

With a modified DSLR, red channel is dominant. I was expecting to capture more OIII section of IC1396. I guess Astro OSC camera shows better OIII and Ha balance thru NB1.

I will try same target with NB2 & 3 next time.
